Damien George d0a5bf34f7 py: Tidy up returning NULL which should be MP_OBJ_NOT_SUPPORTED. 2014-05-10 13:55:11 +01:00
Damien George ccc85ea0da py: Combine native emitters to 1 glue function; distinguish viper.
This patch simplifies the glue between native emitter and runtime,
and handles viper code like inline assember: return values are
converted to Python objects.

Fixes issue #531.

Damien George 3417bc2f25 py: Rename byte_code to bytecode everywhere.
bytecode is the more widely used.  See issue #590.

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Paul Sokolovsky 7a14022604 Merge pull request #552 from stinos/mingw-alloca
py: Use <alloca.h> for alloca()
2014-05-03 14:39:47 +03:00
Paul Sokolovsky 418aca976c objclosure, objcell: Print detailed representation if was requested.
Well, it is bound to "detailed error reporting", but that's closest what we
have now without creating new entities.

stijn 98e2ee0ec1 py: Use <alloca.h> for alloca()
alloca() is declared in alloca.h which als happens to be included by stdlib.h.
On mingw however it resides in malloc.h only.
So if we include alloca.h directly, and add an alloca.h for mingw in it's port
directory we can get rid of the mingw-specific define to include malloc.h
and the other ports are happy as well.

Paul Sokolovsky f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it.
Specifically, nlr.h does.

Damien George 2827d62e8b py: Implement keyword-only args.
Implements 'def f(*, a)' and 'def f(*a, b)', but not default
keyword-only args, eg 'def f(*, a=1)'.

Partially addresses issue #524.

Paul Sokolovsky 353b0289f3 py: Add win32-specific header for alloca(). 2014-04-20 22:24:44 +03:00
Damien George a3f94e0030 py: Add arg checking helper functions.
These are to assist in writing native C functions that take positional
and keyword arguments.  mp_arg_check_num is for just checking the
number of arguments is correct.  mp_arg_parse_all is for parsing
positional and keyword arguments with default values.

Damien George b11b85adaa py: Allow to pass buffer protocol flags to get_buffer helper funcs. 2014-04-18 22:59:24 +01:00
Damien George 57a4b4f178 py: Add typecode to buffer protocol.
When querying an object that supports the buffer protocol, that object
must now return a typecode (as per binary.[ch]).  This does not have to
be honoured by the caller, but can be useful for determining element
size.

Damien George 3fd2d7fad2 py: Tidy up function argument error messages.
We are not as verbose as CPython, and maybe a bit too cryptic sometimes.

Paul Sokolovsky f26a30710c objfun: Add local header.
This follows pattern already used for objtuple, etc.: objfun.h's content
is not public - each and every piece of code should not have access to it.
It's not private either - with out architecture and implementation language
(C) it doesn't make sense to keep implementation of each object strictly
private and maintain cumbersome accessors. It's "local" - intended to be
used by a small set of "friend" (in C++ terms) objects.

Damien George 8a1cab952f py: Fix mp_get_buffer, and use it in more places.
Must use mp_obj_get_type to get the type of an object.  Can't assume
mp_obj_t is castable to mp_obj_base_t.

Damien George 8721087661 py: Big improvements to inline assembler.
Improved the Thumb assembler back end.  Added many more Thumb
instructions to the inline assembler.  Improved parsing of assembler
instructions and arguments.  Assembler functions can now be passed the
address of any object that supports the buffer protocol (to get the
address of the buffer).  Added an example of how to sum numbers from
an array in assembler.

Damien George 69b89d21b2 py: Change compile order for default positional and keyword args.
This simplifies the compiler a little, since now it can do 1 pass over
a function declaration, to determine default arguments.  I would have
done this originally, but CPython 3.3 somehow had the default keyword
args compiled before the default position args (even though they appear
in the other order in the text of the script), and I thought it was
important to have the same order of execution when evaluating default
arguments.  CPython 3.4 has changed the order to the more obvious one,
so we can also change.

Damien George 7efc5b3f34 py: Make globals and locals proper dictionary objects.
Finishes addressing issue #424.

In the end this was a very neat refactor that now makes things a lot
more consistent across the py code base.  It allowed some
simplifications in certain places, now that everything is a dict object.

Also converted builtins tables to dictionaries.  This will be useful
when we need to turn builtins into a proper module.

Damien George ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging.
This does not affect code size or performance when debugging turned off.

To address issue #420.

Damien George f78b6df192 py: Disable dump_args function call entirely when not debugging.
Yes, I know, a good compiler will optimise this away, but I feel this is
neater.

Paul Sokolovsky 7fafb28f6d objgenerator: Handle default args to generator functions.

Damien George df6567e634 Merge map.h into obj.h.
Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation.  Thus, the definitions
are now in obj.h instead.  map.h is removed.

Damien George d17926db71 Rename rt_* to mp_*.
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

Damien George bee17b00e3 py: Put n_state for bytecode in the bytecode prelude.
Rationale: setting up the stack (state for locals and exceptions) is
really part of the "code", it's the prelude of the function.  For
example, native code adjusts the stack pointer on entry to the function.
Native code doesn't need to know n_state for any other reason.  So
putting the state size in the bytecode prelude is sensible.

It reduced ROM usage on STM by about 30 bytes :)  And makes it easier to
pass information about the bytecode between functions.

Damien George 0c36da0b59 Implement ROMable modules. Add math module.
mp_module_obj_t can now be put in ROM.

Configuration of float type is now similar to longint: can now choose
none, float or double as the implementation.

math module has basic math functions.  For STM port, these are not yet
implemented (they are just stub functions).

Dave Hylands 51dabac096 Add pin mapping code.
This commit also introduces board directories and moves board
specific config into the appropriate board directory.

boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet
and hand-tweaked.

make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c,
and boards/BOARD-NAME/pins.csv as input and generates the file
build/pins_BOARD_NAME.c

The generated pin file for PYBOARD4 looks like this:
https://gist.github.com/dhylands/9063231

The generated pins file includes all of the supported alternate
functions, and includes upsupported alternate functions as comments.

See the commnet block at the top of stm/pin_map.c for details on
how to use the pin mapper.

I also went ahead and modified stm/gpio.c to use the pin mapper.

Paul Sokolovsky ac2e28c654 Support passing positional args as keywords to bytecode functions.
For this, record argument names along with each bytecode function. The code
still includes extensive debug logging support so far.
